Ficus white scale id

[Tracy]

I have been challenge for a few months with a while scale that shows up on new leafs of my Ficus socotrana.  I have found it doing less damage thus far on other Ficus species including Ficus carica green fruit which is setting as we enter summer.   I have found it on Ficus abutifolia leaves, Ficus palmerii, and even a few spots of white scale, but no damage on Ficus dammaropsis leaves.  My treatment on the Ficus socatrana is to simply rub off the white sandy like scale with my finger when I see spots on newly emerging leaflets.  My two plants (one in ground, one in pot) are still of a size that I can use this method without spending hours chasing it.  I haven't been as diligent with the fruit on my Ficus carica.

Any thoughts on what this is and any suggestions for treatment different than what I am doing.? I haven't tried high pressure water as the leaflets are still soft, and a lighter spray seems to do little.

Looks like dried drops of latex  ..or bird poo  more than some type of insect..  

Occasionally see dried drops like this on adjacent foliage from my Plumeria, Ficus petiolaris, and on leaves of other stuff placed under the microcarpa / nitida out back..

That was my initial thought Nathan.   Unfortunately I ignored it and the leaves would develop the holes where I had initially noticed the white dry sandy gritt.  If I scrape it off, the holes don't develop.   I am not seeing signs of anything else either abaxial or adaxial side of the leaves.  Puzzling to me.

Looks like a fungus. A powdery mildew. Even a rust. Iam no botanist but if the department of primary industries (an Australian government run agricultural inspection agency) where to see it they would say it’s some sort thing that has the potential to wipe millions of dollars in crops. And they would destroy it at your cost giving you the bill for doing so. Try a fungicide perhaps.
